Technical field

The present invention provides a kind of preparation method of high stability amorphous silicic acid cerium, belongs to technical field of preparation for inorganic material.

Background technique

Non-crystalline material have within the scope of minizone atomistic binding is regular, in wider composition range macroscopic properties it is controllable, The features such as homogeneous isotropism, shows some special physicochemical properties, such as mechanical flexibility height, large specific surface area, active sites Abundant, high catalytic activity of point etc., is widely used to the numerous areas such as catalysis, biology, electrochemical energy storage, as optical electrical catalyst, Photoelectric device, lithium battery, functional material etc..But the preparation process of non-crystalline material is complicated at present, the period is long, purity is low.Therefore It is the challenge faced at present as how low cost, the method being simple and efficient largely prepare non-crystalline material.

Metallosilicate material rich reserves in nature, environmental-friendly, chemical property is stablized, and industrial applications are wide It is general, as ferrosilite as adsorbent the selective absorption dye of positive ion from waste water；Manganous silicate is as T₁Mode contrast agent improves Magnetic resonance imaging quality；Cupric silicate is as catalyst for hydrogenation reaction etc..

However the report not prepared in the prior art about high stability amorphous silicic acid cerium also.In order to utilize non-crystalline material The excellent physicochemical property with silicate material, the present invention provides a kind of sides of efficiently preparation high stability amorphous silicic acid cerium material Method has great importance for the further application of silicic acid cerium material.

Summary of the invention
